ME3600 does not automatically copy DSCP into COS
ME3600 does not automatically copy DSCP into COS and also does not automatically copy EXP into COS T-T
Hi all,
I found the problem my customer’s TOS is rewritten.
Topology:
Tester1 (Send CoS=5) — Gi0/0/1/0 ASR9k 0/0/1/0.3604 — xconnect — Gi0/9 ME-3600X Gi0/24 — Gi0/14 ME-3400 Gi0/5 — Tester2 (rx CoS=0)
I open the TAC both ASR and ME Switch Team and this is the answer from ME Switch Team:
ME3600 does not automatically copy DSCP into COS and also does not automatically copy EXP into COS as described in the following document which was presented on Cisco Live event (page 44 and 45):

Solution:
Please configure policy-map on interfaces to set a proper COS value basing on incoming DSCP.
